How To: Redirect to a specific page on successful sign up (registration)

The proposed way is available since Devise 1.2.rc.

1. Make a new controller "Registrations" and customize the appropriate method:

class RegistrationsController < Devise::RegistrationsController
  protected

  def after_sign_up_path_for(resource)
    '/an/example/path'
  end
end

If the account that is registered is not active yet, you have to override after_inactive_sign_up_path_for method.

class RegistrationsController < Devise::RegistrationsController
  protected

  def after_inactive_sign_up_path_for(resource)
    '/an/example/path'
  end
end

You can see the whole lists of methods to customize on Devise source:

2. Modify config/routes.rb to use the new controller

devise_for :users, :controllers => { :registrations => "registrations" }

Note: After changing the controller in the config/routes.rb file, you will want to copy over the devise registration views over to the new app/views/registrations path.

Copy the files using "rails generate devise:views". After doing this, you need to copy views/devise/registrations/new.html.erb to views/registrations/new.html.erb Otherwise you will get a "Missing Template" error when you go to users/sign_up
